In Hawaiian mythology, Nāmaka (or Nā-maka-o-Kahaʻi, the eyes of Kahaʻi) appears as a sea goddess in the Pele family. She is an older sister of Pele-honua-mea.
She is the daughter of Ku-waha-ilo and Haumea, whose other children are Pele, the Hiʻiaka sisters, the Kama brothers, and the bird Halulu. Nāmaka takes as her husband ʻAukelenuiaʻīkū, who had arrived in Lalakeenuiakane or in Kahiki (Tahiti), but he later becomes the husband of her sister Pele, and because of this Pele, the Hiʻiaka sisters, Malulani, and Kaʻōhelo migrate to Hawaii. When Pele quarrels with her powerful sister Nāmaka, Nāmaka sends tidal waves to destroy Pele's lands and homes. Helped by her family, Pele fights Nāmaka, but Nāmaka defeats her.
